I have a question? I was hooked to 50 amp in a park in Denver, NC. 2 weeks ago I had a surge gard in place and the a/C running. after 1/2 hr we went to supper and gone about 2 hrs. MH was cooling down fine when I left. Upon return my a/c unit and area around MH was stinking of burnt Oil(capacitor smell) a/c running but not cooling. all breakers on and surgegard normal. When we returned to home(Brick House) we put it in the shop. Tech said it burnt up 2 run capacitors 1 start capacitor, printed circuit board, harness to ac from capacitor back through unit. Tech said low voltage caused the damage. all breakers were still set. surgegard normal had 12v to board and blinking. What Happenend?
I would say more likely the compressor run cap just failed. This would bring the compressor to a stall. Then the start cap circuit will keep trying to restart untill it fried itself and its wiring from the heavy current. Low voltage yes,but less likely.
However I'm wondering why the compressor thermo protection didn't seem to work.
